COUPLlNG-HEAD 'FoR SODA-TANKS.

SPECIFICATION forming part of Letters PatentNo. 770,570, dated September20, 1904.

Application filed April 26, 1904. Serial No. 204,941. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES A. Gnnnns, a citizen of the United States,residing in the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania, have invented a new and useful Improvement in Coupling-Heads for Soda-Tanks, of which the following is a specification.

My invention relates to coupling-heads for soda-tanks. I

It comprises means whereby the head may be instantly connected with thetank, whereby the escape of the charged liquid and gas is largelyprevented. v 1

It further consists of novel features of construction, all as will behereinafter fully set forth.

Figure 1 represents in top plan view a head embodying my invention. Fig.2 is a vertical section thereof. Fig. 3 is a transverse section throughthe line or w, Fig. 1.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a valve-casing, to which issecured a threaded coupling 2, from which in practice depends a tubularstem or leg (not shown) adapted to reach to the lower end of asoda-tank. Apertures 3 4 in the coupling2 and casing 1, respectively,lead to the valve-chamber 5. VVithin the chamber 5 is a tubular stem 6,the longitudinal bore 7 of which connects by means of lateral ports 8with the valve-chamber 5. The head 9 of the stem 6 reciprocates withinan internal collar 10 in the body 1, whereby the lateral ports 8 arealternatively opened and closed. The thrust-spring 11 serves to hold thevalve in its closed position. At one end of the valve-casing 1 areprovided concentric annular flanges 12 13, forming between them anannular groove 14:. As will be seen in Fig. 2 of the drawings, the end15 of the valve-casing is open, exposing the end of the tubular stem 6.The other end, 16, of the casing 1 is closed by a plug 17.

Secured to the inner end of the stem 6 is a portion 18, having anannularflange l9 adapted to bear against a portion when the valve isclosed.

Detachably connectedwith the casingl is a yoke 21, provided at one endwith a threaded boss 22, within which plays a stem 23, havingathrea-d'ofquick pitchand having mounted at its outer end a lever or wrench 24:. Atthe opposite end of the frame or yoke 21 is pivotally mounted a block25, to which is connected a lateral tube 26: The bore of the tube 26connects with an axial bore 27 in the block 25. *At the inner end of theblock are concentric annular flanges 28 29, forming between them agroove30. An annular packing 31 is placed within the groove 30 and a smallerannular packing within the flange 28. As clearly shown in Fig. 2 of thedrawings, the bore 7 of the valve-stem- 6 and the bore 27 of the block25 are in alinement when the parts are connected, the packing-washer 31forming a part of the tubular passage. Lugs 32 on the frame 21 rest onthe valve-casing 1 and serve to support the frame in position.

The operation is as follows: The yoke 21 and connected parts beingremoved from the valve-casing 1, it is evident that by the action ofthespr'ing 11 the. valve-stem will be forced to the left of the drawing,so that the ports 8 will bewithin the collar 10 and the valve willbeclosed. After the coupling 2 has been screwed into the soda-tank and thetube 26 connected with the draft-cock the yoke 21. is placed inposition, as shown, and the lever 24 given a very quick movement in thedirection of the arrow, Fig. 3. The rotation of the screw 23, the innerend of which presses against the closed end of the valvecasing 1, servesto draw the block 25 into instant contact with the casing 1, as shown inFig. 2 of the drawings. This acts to force the flange 12 against thepacking 31 and to force the stem 6 to the position shown in Fig. 2, sothat the ports. 8 are in free communication, through the chamber 5 andpassages 4: and 3, with the tank.

I have shown the bore 33 of the tube 26 as enlarged to form a shoulderedvalve-seat 34, on which rests a ball-valve 35, which is retained inposition by a cross-rod 36 or by any wellknown device. The ball risesfreely from its seat under the pressure of the fluid, but

acts to prevent any return flow from the drafttube when the block 'isdisconnected from the casing 1. The reduced end 37 of the tube 25 isadapted to have the tube which leads to the fountain soldered orotherwise attached thereto without overheating or in any way interferingwith the valve 35.

The great advantage of my device lies in the speed with which theconnection is made, whereby practically all escape of charged liquid orgas is prevented and whereby the connection can be as easily brokenwithout loss of gas or water. The single lever 24, acting on thequick-pitched screw 23, enables the operator by a single motion of hishand to connect or disconnect the device.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A coupling-head for soda-tanks compris- 7 ing a valve-casing providedwith means for connecting it to the tank and with alongitudinally-movable tubular valve-stem, a block having a bore adaptedto cooperate with said tubular stem, a draft-tube secured to said block,a yoke adapted to connect said valvecasing to. said block, and a screwof quick pitch in said yoke and provided with a lever for instantlyengaging said block with said valve-stem and for reciprocating thelatter.

2. Acoupling-head for soda-tanks comprising a valve-casing, means forcoupling said casing to the tank, a longitudinally-movable connected tosaid block, a screw of quick pitch in said yoke and adapted to bearagainst the closed end of said casing, and a laterallyextending lever onsaid screw, whereby said block and said casing may be instantlyconnected and said valve-stem moved to open the valve.

3. A coupling-head for soda-tanks provided with means for connecting itto the tank and with a longitudinally-movable tubular valvestem,. ablock having a bore adapted to cooperate with said tubular stem, adraft-tube secured to said block, a yoke adapted to connect saidvalve-casing to said block, a screw of quickpitch in said yoke andprovided with a lever for instantly engaging said block with saidvalve-stem and for reciprocating the latter, and a ball-valve andvalve-seat in said draft-tube.
